How was arsenic discovered?
The Greek philosopher Theophrastus knew of two arsenic sulfide minerals: orpiment (As2S3) and realgar (As4S4). When this was mixed with olive oil and heated it yielded arsenic metal itself. The discovery of the element arsenic is attributed to Albertus Magnus in the 1200s.

Who discovered dysprosium?
Paul-Émile Lecoq de Boisbaudran
Dysprosium/Discoverers
Dysprosium was discovered in 1886 by Paul-Émile Lecoq de Boisbaudran in Paris. Its discovery came as a result of research into yttrium oxide, first made in 1794, and from which other rare earths (aka lanthanoids) were subsequently to be extracted, namely erbium in 1843, then holmium in 1878, and finally dysprosium.
Where was arsenic discovered in what country?
Mineral forms of arsenic were known as early as the fourth century BC, but the German scholastic Albertus Magnus is usually accredited with the discovery of the element around 1250.
